Never having actually seen a Magic Dock before, the Clark location being relatively close, and having spare time, took a drive up there and took a look.
Parked nearby, walked up to an open stall, and, out of curiosity, unhooked the NACS cable - and the Magic Dock adapter came out with it!
Took a couple of pictures, nothing surprising:
Put it back in, tried unhooking it again, and, this time, the NACS came out but the adapter stayed put.
More interestingly, a fellow actually charging next to where I was fiddling around came up and said, "What the heck
is that?", at which point I explained about Magic Docks.
He then told me something was wrong and it was going to take him three hours (!) before he could go on his way. Some quick looking at his screen (state of charge: 7%) showed it charging at 30 kW, pretty low for a 250 kW Supercharger. Told him, "It's broken! Try a different stall!"
At which point he took my advice, went about five stalls down and around the corner and, ta-da! charging at 234 kW. And three minutes to go before he could leave for his destination 'way down south.
Apparently the Tesla NAV software routed him here rather than to the (somewhat further from the Garden State Parkway) WaWa down in Woodbridge. Which would've been fine, except for the low charge rate. Apparently, this is the first time this fellow's run into a dead, or partly dead, Supercharger stall.
I imagine Tesla will get to the malfunctioning ones sooner than later.
